Exact VRAM memory allocation, dynamic KV-cache requirements, and tensor parallelism slicing for Qwen-2.5 32B Coder & Math quantized in GPTQ 4-Bit Second-Order deployed on NVIDIA L40S 48GB Ada Lovelace.

🎛️ Architecture & System Parameters
Reactive Compute Engine

Engineering Execution Protocol

  1. Set model parameter size (32.5B) and verify GPTQ 4-Bit Second-Order quantization precision.
  2. Define production context length in tokens and peak concurrent query concurrency.
  3. Evaluate required memory capacity and calculate multi-GPU tensor parallelism scaling across NVIDIA L40S 48GB Ada Lovelace nodes.

Technical Authority & System Specifications

Q: How much VRAM does Qwen-2.5 32B Coder & Math require in GPTQ 4-Bit Second-Order?

Uncompressed weights alone consume 16.2 GB. In addition, the KV cache scales with context tokens and concurrency batch size, plus ~1.8 GB CUDA driver overhead.

Q: Can a single NVIDIA L40S 48GB Ada Lovelace run this model without Out-Of-Memory (OOM)?

If total weights + KV cache exceeds the 48 GB boundary, Tensor Parallelism (TP) or vLLM PagedAttention multi-GPU sharding across NVLink is required.

Q: How does 4-bit quantization affect inference quality and speed?

Modern AWQ and GPTQ retain >98% perplexity compared to FP16 while halving memory footprint and doubling memory-bandwidth-bound token generation speed.
